Abstract: A method of producing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a medium pore size of at least about 10 nm with an acid to produce a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support to produce a noble metal-containing silica support, and optionally contacting the noble metal-containing silica support with a chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as, phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.
